NoMethodError: undefined method `has_attached_file'

Paperclip produces this error, after checking out the plugin's rails3 branch. My Gemfile has following line: 

gem 'paperclip', :git => 'http://github.com/thoughtbot/paperclip.git', :branch => 'rails3'

And the error message is: 

NoMethodError: undefined method `has_attached_file' for #<Class:0x2a50530>

I have a paperclip fork, you can try if it will work at your end, just change your Gemfile:

gem 'paperclip', :git => 'git://github.com/lmumar/paperclip.git', :branch => 'rails3'

Don't forget to run bundle install after updating your Gemfile.

Hope it will fix your problems.

That didn't work for me. I have done below things and it is working perfectly:

  • Add "Paperclip::Railtie.insert" in application.rb
  • Add "config.gem 'paperclip'" in development.rb

Update 06-21-10: the thoughtbot version has been fixed.

I had to add Paperclip::Railtie.insert to my application.rb at the end of class Application < Rails::Application to get it to work correctly. I have deleted my fork since the official repo is working. Hope that helps someone.

You will also need to add the following to your Gemfile

gem "paperclip", :git => "http://github.com/thoughtbot/paperclip.git"
